When selecting M16 hardware for lifting, mounting, or securing projects, understanding material quality, thread specifications, and corrosion resistance matters. The following five products cover common M16 applications—from eyebolts to flange bolts—each built with durable materials and standard 2 mm pitch. Use this guide to compare options, ensure compatibility with your project, and choose hardware that balances strength, longevity, and ease of use.

Eowpower M16 Eyebolts Set
Eowpower provides a compact eybolt pair designed for lifting or securing components with a 304 stainless steel build. The set features M16 threads and a ring inner diameter suitable for medium-duty applications. These eyebolts are designed to resist corrosion in typical workshop environments, making them suitable for DIY projects, light construction, and marine or outdoor use where stainless steel benefits are desirable. The pair format supports balanced load distribution for stable attachments.
uxcell M16-2x35mm Flange Bolts
uxcell’s M16 flange bolts in 2x35mm provide a robust, high-strength option in 10.9 grade carbon steel with a black oxide coating. The flange diameter and under-head length are tuned for secure assemblies in machinery, DIY projects, and household installations like guardrails and pipe fittings. The set’s high wear resistance and anti-corrosion finish help maintain thread integrity under repetitive use, making them suitable for temporary or semi-permanent fixtures where frequent disassembly is anticipated.
uxcell M16-2x50mm Flange Bolts
This 2x50mm option from uxcell extends the same 10.9 grade carbon steel, black oxide coating, and corrosion resistance with a longer under-head segment. Aimed at projects requiring extended engagement length, these bolts support heavier loads and longer spans in fencing, frames, or equipment mounts. The larger flange diameter helps distribute load more evenly, reducing the risk of pull-through in soft or hollow substrates.
Glarks M16 Heavy Duty Eyebolts Set
Glarks combines 304 stainless steel eyebolts with a complete hardware set including lock nuts, lock washers, and flat washers. The 8-piece kit provides two eyebolts plus mounting hardware, ensuring stable attachment points for lifting, rigging, or securing loads in industrial or workshop settings. The stainless composition offers strong corrosion resistance, making these suitable for humid or coastal environments where rust resistance is essential. The included washers help mitigate loosening during dynamic loading.
Buying Guide: Key Purchase Considerations
- Material and corrosion resistance: Stainless steel (304) offers better corrosion protection in humid environments, while carbon steel with a black oxide finish is common for budget or indoor use. Choose based on exposure and load requirements.
- Thread size and pitch: M16 with a 2 mm pitch is standard for many M16 accessories. Confirm compatibility with your existing hardware and ensure proper threading for safe assembly.
- Load capacity and safety factors: Eyebolts and heavy-duty fasteners should be selected with load ratings in mind. Consider dynamic loads, vibration, and potential shock when selecting hardware.
- Under-head length and flange diameter: Longer under-head lengths provide deeper engagement, while flange dimensions influence load distribution and seating surfaces. Ensure the substrate can accept the chosen dimensions.
- Finish and coatings: Black oxide offers modest corrosion resistance and cost benefits; stainless steel provides superior resistance for harsh environments. For outdoor or marine uses, stainless variants are generally preferred.
- Pack size and compatibility: Kits with washers and lock nuts improve secure connections and reduce loosening due to vibration. Verify that the included hardware matches your application’s metrics.
- Installation considerations: Reusable or reusable-with-locking hardware increases reliability in adjustable setups, while fixed fasteners suit permanent installations. Always follow manufacturer torque recommendations and safety guidelines.
- Cost vs. value: While stainless hardware may cost more upfront, its longevity in corrosive settings often yields lower total cost of ownership through less frequent replacements.
When choosing between the listed options, consider your environmental conditions, load expectations, and whether you need corrosion resistance versus cost efficiency. For projects exposed to moisture or salt air, prioritize stainless steel eyebolts. For indoor or controlled environments, high-strength carbon steel flange bolts provide solid performance at a lower price point. The Glarks kit is advantageous when you want a bundled solution with mounting hardware, while the uxcell options cover different lengths for varied installation depths.
